DETAILED DESCRIPTION

[0074] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0076] Electronic devices such as mobile phones and tablet computers have become indispensable technological products in people's lives, learning and entertainment, bringing a lot of convenience and fun to people's lives. With the development of diversified functions of electronic devices, there are many types and brands of electronic devices, which makes it possible for consumers to choose from a lot of electronic devices. Simply improving the functional characteristics of electronic devices cannot meet people's requirements for electronic devices. The aesthetics of the shell structure of electronic devices has also become an important factor affecting the competitiveness of electronic products. Among electronic devices with similar functions or performance, the better the durability of the electronic device, the more attractive it is to consumers to buy.

[0077] As the application of flexible display screens becomes more and more mature, their application in electronic devices is becoming more and more extensive. Foldable electronic devices using flexible display screens can be folded in half for easy carrying; and when the flexible display screen is unfolded, it has a larger display area, which is becoming more and more popular among consumers.

[0078] However, in the related technology, a mechanical folding mechanism is required to fold the flexible display screen to ensure that there is no malfunction during the normal use of the flexible display screen and that the normal bending of the flexible display screen is not affected; at the same time, the folding mechanism cannot damage the flexible display screen. However, due to structural defects, for example, in the folded state, the overlap of related parts is small, which is prone to shaking, and is not conducive to improving the user experience of foldable electronic devices.

[0079] Based on this, the present disclosure provides a folding mechanism which is not prone to shaking and is conducive to improving the user experience of a foldable electronic device.

[0080] In order to better understand the folding mechanism of the present invention, an explanation is given through a foldable electronic device to which the folding mechanism is applied.

[0081] like Figures 1 to 7 The structure diagram of the foldable electronic device and the folding mechanism shown in some embodiments is shown. Figure 1 Schematic diagram of the structure of a foldable electronic device shown in one embodiment (the flexible display screen is in an unfolded state). Figure 2 Schematic diagram of the structure of a folding mechanism shown in an embodiment (the folding mechanism is in an unfolded state). Figure 3 for Figure 2 A front view schematic diagram of the folding mechanism shown. Figure 4 for Figure 3The folding mechanism shown is a half-section schematic diagram cut along a first cutting direction. Figure 5 for Figure 3 The folding mechanism shown is a half-section schematic diagram cut along the second cutting direction. Figure 6 for Figure 2 The schematic diagram of the structure of the rotating part is shown. Figure 7 for Figure 2 The structure diagram of the folding mechanism shown is shown from the bottom perspective.

[0082] like Figure 1 As shown, in some embodiments of the present disclosure, a foldable electronic device 10 is provided, including a flexible display screen 10a and a folding mechanism 10b, wherein the flexible display screen 10a covers the folding mechanism 10b. The folding mechanism 10b can drive the flexible display screen 10a to switch between an unfolded state and a folded state. When the flexible display screen 10a is in the unfolded state, at least a part of the structure of the folding mechanism 10b can support the flexible display screen 10a.

[0083] Among them, combined with Figures 2 to 5 As shown, the folding mechanism 10b includes a base assembly 100, a support assembly 200, a rotating assembly 300 and a connecting rod assembly 400. One end of the connecting rod assembly 400 is rotatably connected to the base assembly 100. The support assembly 200 is rotatably connected to the other end of the connecting rod assembly 400. The rotating assembly 300 includes a rotating member 310, and the rotating member 310 includes a first connecting body 311 slidably connected to the support assembly 200 and a second connecting body 312 rotatably connected to the base assembly 100. The first connecting body 311 includes a first side 301 and a second side 302 arranged opposite to the first side 301. The first side 301 is provided with a first guide portion 3111 slidably connected to the support assembly 200 and a rotating portion 3112 rotatably connected to the connecting rod assembly 400. The rotating portion 3112 is arranged between the first guide portion 3111 and the second connecting body 312. The second side 302 also includes a second guide portion 3113 slidably connected to the support assembly 200. The matching length between the second guide portion 3113 and the support assembly 200 is greater than the matching length between the first guide portion 3111 and the support assembly 200 .

[0084] When the foldable electronic device 10 is in use, the folding mechanism 10b can drive the flexible display screen 10a to fold or unfold (for example, switch between the unfolded state and the folded state) through the support assembly 200. When the flexible display screen 10a is in the unfolded state, the folding mechanism 10b is in the supporting state, and supports the flexible display screen 10a through the support assembly 200 and the base assembly 100. The support assembly 200 can switch from the supporting state to the folded state, and make the flexible display screen 10a in the folded state. In the process of the rotating member 310 rotating relative to the base assembly 100, the rotating member 310 can drive the bearing member 200a to rotate, and make the first connecting body 311 and the bearing member 200a slide relative to each other. The connecting rod assembly 400 is rotatably connected to the first connecting body 311 through the rotating part 3112, and the first guide part 3111 and the second guide part 3113 are respectively slidably connected to the support assembly 200. And part of the second guide part 3113 is arranged relative to the rotating part 3112 along the direction from the first side 301 to the second side 302. That is, the second guide portion 3113 is extended as much as possible and does not interfere with the rotating portion 3112, so that the matching length between the second guide portion 3113 and the supporting assembly 200 is greater than the matching length between the first guide portion 3111 and the supporting assembly 200, and then when the folding mechanism 10b is in the folded state, the sliding match between the second guide portion 3113 and the supporting assembly 200 has a large overlap, so that the connection strength between the rotating member 310 and the supporting assembly 200 is good. In this way, the shaking of the folding mechanism 10b in the folded state due to the small overlap between the rotating member 310 and the supporting assembly 200 can be effectively avoided, which is conducive to improving the user experience of the foldable electronic device 10.

[0085] It can be understood that the second guide portion 3113 has a good overlap with the support assembly 200, and the provision of the rotating portion 3112 on the first side 301 will not cause a large gap between the first connector 311 and the support assembly 200 to affect the tightness of the fit between the two.

[0086] It should be noted that the first side 301 is generally considered to be a side close to the connecting rod assembly 400 , so as to facilitate the rotational connection between the rotating portion 3112 and the connecting rod assembly 400 .

[0087] In addition, "matching length" should be understood in a broad sense. In the present disclosure, it includes the contact length of the sliding fit between the guide portion and the support assembly 200. That is, in the thickness direction of the support assembly 200, when the folding mechanism 10b is in the folded state, the overlap between the second guide portion 3113 and the support assembly 200 is greater than the overlap between the first guide portion 3111 and the support assembly 200.

[0088] Specifically, Figure 5As shown, the matching length between the first guide portion 3111 and the support assembly 200 is L1, and the matching length between the second guide portion 3113 and the support assembly 200 is L2, wherein L2>L1.

[0089] It should be noted that there are many specific implementations of the connecting rod assembly 400. For example, the connecting rod assembly 400 is a watch strap. For example, the connecting rod assembly 400 includes multiple connecting rods.

[0090] It should be noted that when the flexible display screen 10a is in the unfolded state, the carrier 200a is in the supporting state and can support the effective display screen. When the flexible display screen 10a is in the folded state, the carrier 200a is in the folded state.

[0091] In some embodiments, the supporting assembly 200 includes a bearing member 200a slidably connected to the first connecting body 311. In this way, the bearing member 200a can be driven to rotate by the rotating member 310 to support or avoid the flexible display screen 10a.

[0092] like Figure 2 as well as Figure 3 As shown, in some embodiments, when the carrier 200a is in the supporting state, the carrier 200a and part of the base assembly 100 slide together to form a supporting surface for supporting the flexible display screen 10a. In this way, the flexible display screen 10a can be better supported by the supporting surface in the unfolded state, so as to facilitate viewing or touch by the user.

[0093] Alternatively, if Figure 4 as well as Figure 5 As shown, in some embodiments, when the carrier 200a is in the folded state, the carrier 200a and the base assembly 100 are arranged at an acute angle to form an escape space. In this way, the flexible display screen 10a is easy to bend in the escape space, so that the flexible display screen 10a can be folded smoothly and is not easily damaged.

[0094] It can be understood that when the supporting member 200a switches from the supporting state to the folding state, the supporting member 200a is slidably connected to the rotating member 310 so that the supporting member 200a moves away from the base assembly 100 to form an escape space.

[0095] Optionally, in some embodiments, the carrier 200a is slidably connected to at least two rotating members 310. In this way, during the rotation of the foldable electronic device 10, at least two rotating members 310 are used to drive the carrier 200a to move, so that the force on the carrier 200a is more uniform, and the flexible display screen 10a can be easily replaced to support or avoid it.

[0096] Optionally, the carrier 200a includes a floating plate. In this way, by using the floating plate, the thickness of the folding mechanism 10b is reduced, which is conducive to achieving a lighter and thinner foldable electronic device 10.

[0097] It should be noted that there may be many specific implementations of the rotational connection between the rotating portion 3112 and the connecting rod assembly 400, including but not limited to hinge connection, shaft connection, etc.

[0098] In some embodiments, one of the rotating part 3112 and the connecting rod assembly 400 is provided with a rotating protrusion, and the other is provided with a matching hole 303 that is rotatably matched with the rotating protrusion. In this way, the rotating part 3112 and the connecting rod assembly 400 are rotatably connected by the rotating protrusion and the matching hole 303, so that the connection between the two is more compact and easy to implement.

[0099] The rotating convex body includes a shaft body, a convex rod and the like.

[0100] Alternatively, if Figure 4 As shown, in some embodiments, the connecting rod assembly 400 is provided with a rotating protrusion, and the first side 301 is provided with a matching hole 303. In this way, the first side 301 is provided with a matching hole 303, which facilitates the sliding connection between the first guide portion 3111 and the carrier 200a, and the structure is more compact. The connecting rod assembly 400 is provided with a rotating protrusion, which is convenient for realization by using the protruding rotating shaft and is also easy to implement. In turn, the folding mechanism 10b is easy to manufacture and has a low manufacturing cost.

[0101] like Figure 6 As shown, optionally, the matching hole 303 is a blind hole. In this way, the rotating protrusion will not pass through the first connecting body 311 and extend to the second side 302, and will not interfere with the sliding connection between the second guide portion 3113 and the support assembly 200. In addition, the second guide portion 3113 can also be provided in the depth extension direction of the matching hole 303, so that the extension length of the second guide portion 3113 can be guaranteed to have a good overlap with the support assembly 200.

[0102] In some other embodiments, the rotating protrusion is disposed on the rotating portion 3112 , and the matching hole 303 is disposed on the connecting rod assembly 400 .

[0103] In combination with any of the above embodiments, Figure 5As shown, in some embodiments, part of the second guide portion 3113 is arranged opposite to the rotating portion 3112 along the direction from the first side 301 to the second side 302, so that the length of the second guide portion 3113 is greater than the length of the first guide portion 3111. In this way, relative to the first side 301, the area of ​​the first side 301 where the rotating portion 3112 is arranged, and the second guide portion 3113 can also be arranged on the second side 302, so that the length of the second guide portion 3113 is greater than the length of the first guide portion 3111, and further, the matching length of the second guide portion 3113 and the support assembly 200 is greater than the matching length of the first guide portion 3111 and the support assembly 200.

[0104] In particular, when the folding mechanism 10b is in the folded state and parts of the first guide portion 3111 and the second guide portion 3113 are separated from the support assembly 200, the mating length of the second guide portion 3113 and the support assembly 200 is greater than the mating length of the first guide portion 3111 and the support assembly 200, so that the rotating member 310 and the support assembly 200 still have a good connection strength, making it difficult for the folding mechanism 10b to shake or get stuck in the folded state.

[0105] In combination with the above-mentioned embodiment of the carrier 200a, Figure 5 As shown, in some embodiments, the carrier 200a includes a first matching portion 210 that is slidably matched with the first guide portion 3111 and a second matching portion 220 that is slidably matched with the second guide portion 3113. When the support assembly 200 is in a folded state, the matching length between the second guide portion 3113 and the second matching portion 220 is greater than the matching length between the first guide portion 3111 and the first matching portion 210. In this way, the thickness space of the carrier 200a is fully utilized to set the first matching portion 210 and the second matching portion 220, and it is easy to achieve that the matching length between the second guide portion 3113 and the second matching portion 220 is greater than the matching length between the first guide portion 3111 and the first matching portion 210, so that even if the first connecting body 311 is provided with the rotating portion 3112, it can have a good overlap with the carrier 200a, so that the connection strength between the rotating member 310 and the carrier 200a is good.

[0106] In addition, the thickness space is used to accommodate part of the first connecting body 311, so that the structure of the folding mechanism 10b is more compact.

[0107] like Figure 5As shown, in some embodiments, a portion of the second guide portion 3113 and a portion of the second matching portion 220 are arranged relative to the rotating portion 3112 along the direction from the first side 301 to the second side 302, so that the length of the second guide portion 3113 is greater than the length of the first guide portion 3111, and the length of the second matching portion 220 is greater than the length of the first matching portion 210. In this way, relative to the first side 301, the area where the rotating portion 3112 is arranged on the first side 301, and the second guide portion 3113 can also be arranged on the second side 302, so that the length of the second guide portion 3113 is greater than the length of the first guide portion 3111. The second matching portion 220 is also extended accordingly, so that the matching length of the second guide portion 3113 and the support assembly 200 is greater than the matching length of the first guide portion 3111 and the support assembly 200.

[0108] In particular, when the folding mechanism 10b is in the folded state and the first guide portion 3111 and the second guide portion 3113 are partially separated from the supporting member 200a, the mating length between the second guide portion 3113 and the second matching portion 220 is greater than the mating length between the first guide portion 3111 and the first matching portion 210, so that the rotating member 310 and the supporting assembly 200 still have good connection strength, making it less likely for the folding mechanism 10b to shake or get stuck in the folded state.

[0109] Specifically, Figure 5 As shown, the matching length between the first guide portion 3111 and the first matching portion 210 is L1, and the matching length between the second guide portion 3113 and the second matching portion 220 is L2, wherein L2>L1.

[0110] Specifically, 1.1L1≤L2≤2.5L1.

[0111] Optionally, L2=1.1L1, 1.2L1, 1.3L1, 1.4L1, 1.5L1, 1.6L1, 1.7L1, 1.8L1, 1.85L11.1L1, 1.55L1, 2L1.

[0112] In some embodiments, one of the first guide portion 3111 and the first matching portion 210 is provided with a first slide rail, and the other of the first guide portion 3111 and the first matching portion 210 is provided with a first slide groove 211 that slidably matches with the first slide rail. In this way, through the cooperation between the first slide groove 211 and the first slide rail, the carrier 200a and the first connecting body 311 are closely matched, which is conducive to reducing the thickness of the folding mechanism 10b.

[0113] In some embodiments, one of the second guide portion 3113 and the second matching portion 220 is provided with a second slide rail, and the other of the second guide portion 3113 and the second matching portion 220 is provided with a second slide groove 221 that slidably matches with the second slide rail. In this way, through the cooperation between the second slide groove 221 and the second slide rail, the carrier 200a and the first connecting body 311 are closely matched, which is conducive to reducing the thickness of the folding mechanism 10b.

[0114] It should be noted that the specific shapes of the first slide rail and the second slide rail can be various, such as rectangular, trapezoidal, partially circular or partially elliptical in cross section, etc., as long as they can meet the use requirements, and no excessive restrictions are made here.

[0115] In combination with the above-mentioned embodiment of the first slide rail, Figure 5 As shown, in some embodiments, the first guide portion 3111 is provided with a first slide rail, the first slide rail includes a first rail body 304, a second rail body 305, and a stopper 308 spaced apart from the rotating portion 3112, the first rail body 304 is disposed between the rotating portion 3112 and the stopper 308, and the second rail body 305 and the first rail body 304 are spaced apart on both sides of the stopper 308. When the support assembly 200 is in a folded state, the stopper 308 cooperates with the stopper of the connecting rod assembly 400 to limit the support assembly 200 from continuing to rotate in the folding direction of the folding mechanism 10b. In this way, the stopper 308 cooperates with the stopper of the connecting rod assembly 400 to limit the support assembly 200 from continuing to rotate in the folding direction of the folding mechanism 10b, thereby preventing the folding mechanism 10b from being over-folded and causing damage to parts or separation and failure of related parts.

[0116] There may be many specific implementations of the stopper 308 and the connecting rod assembly 400, including but not limited to the limiting locking fit between the card body and the card hole, the blocking fit between the convex body and the blocking block, the limiting fit between the limiting protrusion 309 and the limiting recess, etc.

[0117] Alternatively, if Figure 5 as well as Figure 6 As shown, in some embodiments, the connecting rod assembly 400 includes a first connecting rod 410 rotatably connected to the supporting assembly 200, the first connecting rod 410 is provided with a limiting protrusion 411, and the stopper 308 is provided with a limiting groove 3081. When the supporting assembly 200 is in a folded state, at least a portion of the limiting protrusion 411 is clamped in the limiting groove 3081, so that the stopper 308 and the connecting rod assembly 400 are stopped and matched. In this way, the first connecting rod 410 is used to realize the rotational connection between the connecting rod assembly 400 and the supporting assembly 200, and the limiting protrusion 411 provided on the first connecting rod 410 cooperates with the limiting groove 3081 to realize the stopping cooperation between the stopper 308 and the connecting rod assembly 400, and the structure is compact, which is conducive to realizing the miniaturization of the folding mechanism 10b and the foldable electronic device 10.

[0118] Furthermore, if Figure 6 As shown, in some embodiments, the first rail body 304 includes a first end 3041 disposed in the limiting groove 3081, and at least one of the first end 3041 and the outer surface of the limiting protrusion 411 is provided with a guide surface 3042 for guiding the limiting protrusion 411 into the limiting groove 3081. In this way, the limiting protrusion 411 can be better guided into the limiting groove 3081 by using the guide surface 3042, so that the limiting protrusion 411 and the limiting groove 3081 are limitedly matched, so as to realize the stopping cooperation between the stopper 308 and the connecting rod assembly 400. This makes the stopping movement of the folding mechanism 10b in the folded state smoother, and the operation of the folding mechanism 10b is smoother.

[0119] Alternatively, if Figure 6 As shown, in some embodiments, the second rail body 305 includes a second end 3051 disposed opposite to the first end 3041; when the support assembly 200 is in the folded state, the second end 3051 abuts against a portion of the limiting protrusion 411, so that the limiting protrusion 411 is engaged with the stopper 308. In this way, the second end 3051 abuts against a portion of the limiting protrusion 411, so that the limiting protrusion 411 is engaged with the stopper 308, which can further improve the reliability of the engagement between the stopper 308 and the connecting rod assembly 400.

[0120] It should be noted that the specific structure of the limiting protrusion can be various, for example, the limiting protrusion is in the shape of a convex hull, a rod, a column, a block, etc.

[0121] In combination with any of the above embodiments of the carrier 200a, Figure 6 as well as Figure 7 As shown, in some embodiments, the support assembly 200 has a supporting state in which it cooperates with the base assembly 100 to form a supporting surface; when the support assembly 200 is in the supporting state, the rotating member 310 and the support assembly 200 are locked and matched, so that the support assembly 200 and the base assembly 100 are matched to form a supporting surface. In this way, the flexible display screen 10a can be reliably supported by the locking cooperation of the rotating member 310 and the support assembly 200, so that the support assembly 200 and the base assembly 100 are matched to form a supporting surface, and the folding mechanism 10b is prevented from being over-expanded, resulting in damage to parts or failure of related parts due to separation, or even damage to the flexible display screen 10a.

[0122] It should be noted that there are many ways to implement the locking cooperation between the rotating member 310 and the supporting assembly 200. For example, a limiting structure is provided between the second connecting body 312 and the supporting member 200a to prevent the folding mechanism 10b from unfolding too much, so that the supporting assembly 200 and the base assembly 100 cooperate to form a reliable supporting surface.

[0123] like Figure 6 as well as Figure 7 As shown, in one example, the first connector 311 further includes a first limiting portion 3114, and the carrier 200a further includes a second limiting portion 230. When the support assembly 200 is in the supporting state, the first limiting portion 3114 abuts against the second limiting portion 230, so that the rotating member 310 and the carrier 200a are stopped and matched. In this way, the first limiting portion 3114 abuts against the second limiting portion 230, so that the rotating member 310 and the carrier 200a are stopped and matched, so as to avoid the folding mechanism 10b from being unfolded too far, so that the support assembly 200 and the base assembly 100 cooperate to form a reliable support surface.

[0124] Optionally, in some embodiments, the first limiting portion 3114 is disposed between the first guide portion 3111 and the second guide portion 3113, and the second limiting portion 230 is disposed between the first matching portion 210 and the second matching portion 220. In this way, the space in the width direction of the first connector 311 can be fully utilized to set the first limiting portion 3114, and the space in the length direction of the carrier 200a can be utilized to set the second limiting portion 230, which is easy to implement.

[0125] Optionally, in some embodiments, the first limiting portion 3114 is disposed on the first guide portion 3111, and the second limiting portion 230 is disposed on the first matching portion 210. In this way, the space of the first side 301 of the first connector 311 can be fully utilized to set the first limiting portion 3114, and the second limiting portion 230 can be set in the thickness direction of the carrier 200a, so that the structure of the folding mechanism 10b is compact.

[0126] Optionally, in some embodiments, the first limiting portion 3114 is disposed on the second guide portion 3113, and the second limiting portion 230 is disposed on the second matching portion 220. In this way, the space of the second side 302 of the first connector 311 can be fully utilized to set the first limiting portion 3114, and the second limiting portion 230 can be set in the thickness direction of the carrier 200a, so that the structure of the folding mechanism 10b is compact.

[0127] Based on any of the above embodiments of the first limiting portion 3114, Figure 6 as well as Figure 7 As shown, in some embodiments, one of the first limiting portion 3114 and the second limiting portion 230 is provided with a limiting protrusion 309, and the other one abuts against the limiting protrusion 309 when the carrier 200a is in the supporting state. In this way, by abutting against the limiting protrusion 309, the stop is more reliably achieved, and the folding mechanism 10b is prevented from being over-expanded, so that the supporting assembly 200 and the base assembly 100 cooperate to form a reliable supporting surface.

[0128] It should be noted that the specific structure of the limiting protrusion can be various, for example, the limiting protrusion is in the shape of a convex hull, a hemispherical shape, a columnar shape, a block shape, etc.

[0129] like Figure 6 as well as Figure 7 As shown, in some embodiments, the bearing member 200a includes a bearing surface 201 and a bottom surface 202 arranged opposite to the bearing surface 201, the second limiting portion 230 is arranged between the bearing surface 201 and the bottom surface 202, the rotating member 310 includes a front surface 306 arranged in the same direction as the supporting surface and a back surface 307 arranged opposite to the front surface 306, and the limiting protrusion 309 is arranged on the back surface 307. In this way, the limiting protrusion 309 is arranged on the back surface 307 of the rotating member 310, which will not affect the cooperation between the front surface 306 and the bearing surface 201, so as to better support the flexible display screen 10a.

[0130] like Figure 7 As shown, in some embodiments, on the bottom surface 202, the first matching portion 210 and the second matching surface 3002 extend toward the base frame assembly 100 and form a notch 231, and the second limiting portion 230 is arranged on the side wall of the notch 231. When the support assembly 200 is in the supporting state, the limiting protrusion 309 is arranged in the notch 231 and abuts against the second limiting portion 230. In this way, when the support assembly 200 is in the non-supporting state, the limiting protrusion 309 is avoided by setting the notch 231, so that the connection between the first connecting body 311 and the carrier 200a is tighter. When the support assembly 200 is in the supporting state, the limiting protrusion 309 is arranged in the notch 231 and abuts against the second limiting portion 230. The width space of the carrier 200a is fully utilized to set the second limiting portion 230, thereby making the overall folding mechanism 10b more compact.

[0131] It should be noted that the carrier 200a disclosed in the present invention should be understood in a broad sense, and its specific structure can be various, for example, Figure 8 As shown, the carrier 200a is used to directly support the flexible display screen.

[0132] For another example, Figure 2 or Fig.11 As shown, in some embodiments, the carrier 200a further includes a moving block slidably connected to the rotating member and a floating plate (not shown) disposed on the moving block. In this way, the carrier 200a drives the floating plate to rotate through the moving block, and carries the flexible display screen through the floating plate.

[0133] In combination with any of the above-mentioned embodiments of the carrier 200a, Figure 8As shown, in some embodiments, the folding mechanism further includes a rolling assembly 500. The rolling assembly 500 can be rotatably disposed on at least one of the first connecting body 311 and the carrier 200a, so that at least a portion of the first connecting body 311 and the carrier 200a are rollingly frictionally matched. In this way, when the foldable electronic device 10 is in use, the folding mechanism 10b can drive the flexible display screen 10a to switch between the unfolded state and the folded state through the carrier 200a. When the flexible display screen 10a is in the unfolded state, the folding mechanism 10b is in the supporting state, and supports the flexible display screen 10a through the carrier 200a and the base assembly 100. The carrier 200a can switch from the supporting state to the folded state, and make the flexible display screen 10a in the folded state. During the rotation of the member 310, the rotating member 310 can drive the carrier 200a to rotate, and make the first connecting body 311 and the carrier 200a slide relative to each other. The rolling assembly 500 can be rotatably disposed in the first connecting body 311 and / or the carrier 200a, so that during the sliding process of the first connecting body 311 relative to the carrier 200a, at least part of the first connecting body 311 is engaged in rolling friction with the carrier 200a through the rolling assembly 500, thereby effectively reducing the wear during the sliding process between the first connecting body 311 and the carrier 200a, which is conducive to maintaining the transmission accuracy between the first connecting body 311 and the carrier 200a, and will not easily produce abnormal noise. In this way, the foldable electronic device 10 will not easily produce abnormal noise or shaking after long-term use, and has good durability.

[0134] In order to better understand the technical solution of the present disclosure, the width direction of the carrier is set as the X-axis direction, that is, Fig. 9 As shown, the spacing direction of the two bearing members. The length direction of the bearing member is set to the Y-axis direction, that is, Fig. 9 The thickness direction of the bearing member is set to the Z-axis direction, that is, Fig.10 Section directions shown.

[0135] It should be noted that there may be many specific implementations of the sliding connection between the carrier 200a and the first connecting body 311.

[0136] like Figure 8 as well as Fig.11 As shown, in some embodiments, the carrier 200a is provided with a groove 240 for accommodating the first connector 311. In this way, the thickness space of the carrier 200a is fully utilized to accommodate the first connector 311, so that the first connector 311 is embedded in the carrier 200a, which can reduce the thickness of the folding mechanism 10b, and is conducive to realizing the thinness of the foldable electronic device 10.

[0137] It should be noted that the rolling assembly 500 can be disposed on any side wall of the first connector 311 and / or any side wall of the groove 240, and can achieve at least partial rolling friction fit between the side wall of the first connector 311 and the side wall of the groove 240. In some embodiments, part of the rolling assembly 500 can be rotatably disposed on the side wall of the groove 240, and another part of the rolling assembly 500 can be rolling and friction fit with the slide rail. In this way, part of the rolling assembly 500 can be rotatably embedded in the side wall of the groove 240, and the rolling and friction fit between the first connector 311 and the carrier 200a is achieved through the rolling and friction fit between the other part of the rolling assembly 500 and the slide rail.

[0138] In addition, it can be understood that the thickness of the carrier 200a is usually greater than that of the first connecting body 311. Setting an installation groove on the carrier 200a to accommodate the rolling assembly 500 has little effect on the strength of the carrier 200a, and can fully utilize the thickness space of the carrier 200a to accommodate the rolling assembly 500, making the structure of the folding mechanism 10b more compact.

[0139] And / or, in some other embodiments, part of the rolling assembly 500 can be rotatably disposed on the slide rail, and another part of the rolling assembly 500 is in rolling frictional cooperation with the side wall of the groove 240. In this way, part of the rolling assembly 500 can be rotatably embedded in the side wall of the slide rail, and the other part of the rolling assembly 500 is in rolling frictional cooperation with the side wall of the groove 240, thereby achieving rolling frictional cooperation between the first connector 311 and the carrier 200a.

[0140] Based on any of the above embodiments of the slide rail, Fig.11 As shown, in some embodiments, the groove 240 includes a pressure-bearing surface 241 and a first limit surface 242 disposed adjacent to the pressure-bearing surface 241. The first connector 311 includes a first mating surface 3001 that is slidably matched with the pressure-bearing surface 241 and a second mating surface 3002 that is limitedly matched with the first limit surface 242. Among them, the rolling assembly 500 can be rotatably disposed on at least one of the pressure-bearing surface 241 and the first limit surface 242. And / or, the rolling assembly 500 can be rotatably disposed on at least one of the first mating surface 3001 and the second mating surface 3002. In this way, the pressure-bearing surface 241 and the first mating surface 3001 are slidably matched to realize that the groove 240 carries the first connector 311 to slide. Moreover, the first limit surface 242 and the second limit surface 3002 are limitedly matched to limit the displacement of the first connector 311, so that the first connector 311 can slide along the length direction of the groove 240.

[0141] In addition, the rolling assembly 500 can be rotatably disposed on the pressure-bearing surface 241, the first limiting surface 242, or the pressure-bearing surface 241 and the first limiting surface 242. And / or, the rolling assembly 500 can be rotatably disposed on the first mating surface 3001, the second mating surface 3002, or the first mating surface 3001 and the second mating surface 3002, so as to easily realize the rolling frictional cooperation between the first connecting body 311 and the first connecting body 311, and the implementation method can be flexibly selected according to actual needs.

[0142] Furthermore, if Fig.11 As shown, in some embodiments, there are two first limiting surfaces 242, and the two first limiting surfaces 242 are spaced apart on both sides of the pressure-bearing surface 241; and two second matching surfaces 3002 are spaced apart on both sides of the first matching surface 3001. In this way, through the limiting matching of the two sets of first limiting surfaces 242 and the first matching surfaces 3001, the first connecting body 311 will not deviate left and right, but can slide along the length direction of the groove 240, so as to improve the sliding connection accuracy between the rotating member 310 and the bearing member 200a, and further improve the transmission accuracy of the folding mechanism 10b.

[0143] In any of the above embodiments of the first limiting surface 242, Fig.11 As shown, in some embodiments, the groove 240 also includes a second limiting surface 243 corresponding to the first limiting surface 242, the second limiting surface 243 is adjacent to the first limiting surface 242, and is spaced apart from the pressure-bearing surface 241 to form an anti-slip groove 244, and the first connecting body 311 also includes a third matching surface 3003 that is slidably matched with the second limiting surface 243, and the third matching surface 3003 is spaced apart from the first matching surface 3001 and forms an anti-slip portion 3004 that is anti-slip matched with the anti-slip groove 244. In this way, through the anti-slip cooperation of the anti-slip portion 3004 and the anti-slip groove 244, the first connecting body 311 will not be separated from the groove 240 in the direction away from the pressure-bearing surface 241, which is conducive to improving the reliability of the cooperation between the first connecting body 311 and the groove 240.

[0144] It should be noted that, in the cross-section perpendicular to the sliding direction of the first connector 311, the anti-detachment portion 3004 can have many specific shapes, including but not limited to greater than or equal to 1 / 2 circle, greater than or equal to 1 / 2 ellipse, partial trapezoid, etc., which can limit the first connector 311 from detaching in the direction away from the pressure-bearing surface 241.

[0145] Further, in some embodiments, the rolling assembly 500 can be rotatably disposed on at least one of the pressure-bearing surface 241, the first limiting surface 242, and the second limiting surface 243. And / or, the rolling assembly 500 can be rotatably disposed on at least one of the first mating surface 3001, the second mating surface 3002, and the third mating surface 3003. In this way, it is easy to realize the rolling frictional cooperation between the first connecting body 311 and the first connecting body 311, and the implementation method can be flexibly selected according to actual needs.

[0146] In one example, the rolling assembly 500 can be rotatably disposed in the first limiting surface 242 and the second limiting surface 243, and the first connecting body 311 is sandwiched, so that the first connecting body 311 is clearance-matched with the pressure-bearing surface 241. In this way, the first connecting body 311 is point-to-surface matched with the groove 240 through the rolling assembly 500, ensuring that the wear of the first connecting body 311 during the movement is small, which is conducive to ensuring the transmission accuracy of the rotating member 310 and the bearing member during long-term movement.

[0147] like Fig.12 As shown, in some embodiments, the rolling assembly 500 includes a plurality of rolling bodies 510, at least two rolling bodies 510 are arranged as a first group at intervals along the sliding direction of the first connecting body 311, and at least two rows of the first group are arranged at intervals between the first connecting body 311 and the bearing member 200a. In this way, by arranging at least two rows of the first group at intervals between the first connecting body 311 and the bearing member 200a, it is ensured that the first connecting body 311 has less wear on a single rolling body 510 during the movement, and the transmission accuracy between the first connecting body 311 and the bearing member is effectively prevented from being affected by the wear of the rolling body 510.

[0148] It should be noted that the rolling body 510 may have a variety of specific shapes, including at least one of the existing ellipsoidal sphere, spherical sphere, cylinder, and truncated cone.

[0149] In one example, the rolling element 510 is a spherical ball. Easy to assemble.

[0150] In combination with any of the above embodiments of the groove 240, Fig.13 As shown, in some embodiments, the folding mechanism 10b further includes a limit cover 600, which is fixedly connected to the carrier 200a and covers the groove 240 to limit the first connector 311 from being separated from the groove 240. In this way, the first connector 311 is accommodated by the accommodating cavity, and the limit cover 600 is covered on the groove 240 to limit the rotating member 310 from being separated from the groove 240. It is also convenient to embed part of the first connector 311 into the carrier 200a, reduce the thickness of the folding mechanism 10b, and facilitate the realization of a lightweight and thin foldable electronic device 10.

[0151] Furthermore, in some embodiments, part of the rolling assembly 500 can be rotatably disposed on the limiting cover 600. In this way, the rolling assembly 500 can also be disposed on the limiting cover 600, which is easy to assemble and helps to reduce assembly costs.

[0152] Based on any of the above embodiments, Fig.14 As shown, in some embodiments, the rotating assembly 300 further includes a connecting rod 330 rotatably connected to the connecting rod assembly 400, and the rotating member 310 is movably connected to the connecting rod 330. In this way, by providing the connecting rod assembly 400, it is easy to adjust the spacing between the carrier 200a and the base assembly 100. When the carrier 200a is in the folded state, the connecting rod assembly 400 is used to enlarge the carrier 200a and the base assembly 100 to form an escape space. When the carrier 200a is in the supporting state, the connecting rod assembly 400 is used to shrink the carrier 200a and the base assembly 100 to easily form a tight supporting surface to support the flexible display screen 10a.

[0153] like Fig. 9 as well as Fig.14 As shown, in some embodiments, the base assembly 100 includes a base body 110 and a first mounting rod 120 rotatably disposed on the base body 110, and the rotating member 310 is rotatably connected to the base body 110 through the first mounting rod 120. In this way, the rotating member 310 is rotatably connected to the base body 110 through the first mounting rod 120, so that the base body 110 and the rotating member 310 can be spaced along the length direction of the first mounting rod 120, so that the base body 110 will not interfere with the movement of the rotating member 310, reducing the avoidance space, and making the structure of the folding mechanism 10b more compact and occupying less space.

[0154] Based on the above embodiments, Fig.14 as well as Fig.15 As shown, in some embodiments, one end of the second connecting body 312 is provided with a first matching hole 303 that is rotatably connected to the first mounting rod 120, and the first matching hole 303 is slidably matched with the first mounting rod 120. In this way, through the cooperation between the first matching hole 303 and the first mounting rod 120, it is easy to realize the second connecting body 312 to be rotatably connected relative to the base assembly 100, and can move along the axial direction of the rotation axis.

[0155] Based on the above embodiment of the connecting rod 330, Fig.13 , Fig.15 as well as Fig.17As shown, in some embodiments, the other end of the second connecting body 312 is provided with a second matching hole 303 rotatably connected to the connecting rod 330, and the first matching hole 303 is movably matched with the connecting rod 330. In this way, through the matching of the second matching hole 303 and the connecting rod 330, it is easy to realize the first connecting body 311 to be rotatably connected relative to the base assembly 100, and can move along the axial direction of the rotation axis.

[0156] Based on any of the above embodiments of the second connector 312, Fig.14 As shown, in some embodiments, part of the second connecting body 312 is arc-shaped. In this way, the first installation rod 120 can be avoided better, so as to facilitate the connection rod 330 to move around the outer circumference of the first installation rod 120.

[0157] It should be noted that the "second connecting body 312" can be "a part of the rotating member 310", that is, the "second connecting body 312" and the "other parts of the rotating member 310, such as the first connecting body 311" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the rotating member 310, such as the first connecting body 311", that is, the "second connecting body 312" can be manufactured independently and then combined with the "other parts of the rotating member 310, such as the first connecting body 311" into a whole.

[0158] Equivalently, "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be independently manufactured and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this disclosure is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this disclosure. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this disclosure.

[0159] like Fig.14 as well as Fig.16As shown, in some embodiments, the rotating assembly 300 includes a friction member 320 that is frictionally matched with the rotating member 310, and at least two rotating members 310 are arranged on the first mounting rod 120 at intervals along the length direction of the first mounting rod 120, and the friction member 320 is arranged on the first mounting rod 120 and clamped between two adjacent rotating members 310. In this way, during the rotation of the member 310, the friction member 320 does not rotate with the rotating member 310, so that the friction member 320 and the rotating member 310 are frictionally matched, and then the rotation damping of the rotating member 310 can be increased, so that at least two rotating members 310 need to overcome a certain rotation damping before they can rotate. In this way, when the rotating member 310 is not driven by the rotation force, the bearing member 200a can be fixed on the base assembly 100 to achieve hovering. In addition, the foldable electronic device 10 can better hover in the process of switching between the unfolded state and the folded state, and the operation feel is better, so as to improve the user experience of the foldable device.

[0160] In addition, at least two rotating members 310 are used to move in the same direction to form a synchronous rotating member, and the friction member 320 is used to increase the rotation damping of two adjacent rotating members 310. Thus, the at least two rotating members 310 can drive the bearing member 200a to rotate, thereby ensuring the matching strength between the two. At the same time, the rotation damping of the rotating member 310 can be increased.

[0161] It should be noted that "hovering" can be understood as when the rotating member 310 is not subjected to driving force, it can remain in a certain position, so that a certain rotational force is applied to the rotating member 310 so that the rotating member 310 can rotate. When the rotational force is canceled or reduced, the rotating member 310 can stop rotating and be fixed in a certain position.

[0162] It should be noted that "the support member 200a is connected to at least two rotating members 310" includes direct connection or indirect connection, and the support member 200a can be directly or indirectly driven to rotate by the rotating member 310. For example, the rotating member 310 is slidably connected to the support member 200a. For example, the rotating member 310 is fixedly connected to the support member 200a. For example, the rotating member 310 drives the support member 200a to rotate through other rotating structures.

[0163] It can be understood that the overall damping of the rotating assembly 300 can be flexibly adjusted by adjusting the number of the rotating members 310 and the friction members 320 to achieve the hovering motion of the supporting member 200 a.

[0164] Optionally, the number of the rotating members 310 is more than three, and two adjacent rotating members 310 are each provided with at least one friction member 320 .

[0165] It should be noted that the same-direction movement includes coaxial connection, synchronous same-direction and the like.

[0166] like Fig.10 As shown, at least two rotating members 310 form a group, are coaxially connected and move in the same direction.

[0167] Based on any of the above embodiments of the friction member 320, Fig.15 As shown, in some embodiments, at least two rotating members 310 are fixedly connected to the first mounting rod 120, and the friction member 320 is disposed on the first mounting rod 120. In this way, the first mounting rod 120 is conveniently used to integrate the rotating assembly 300, so that the structure of the rotating assembly 300 is more compact, and the space occupied is small, which is conducive to realizing the thinness of the foldable electronic device 10.

[0168] Based on any of the above embodiments of the friction member 320, combined with the above connecting rod 330, as Fig.13 as well as Fig.17 As shown, in some embodiments, the connecting rod 330 and the first mounting rod 120 are spaced apart along the rotation direction of the rotating member 310, and at least two rotating members 310 are respectively movably connected to the connecting rod 330, so that the at least two rotating members 310 rotate synchronously. In this way, by movably connecting at least two rotating members 310 to the connecting rod 330, it is convenient to realize the synchronous rotation of at least two rotating members 310.

[0169] Based on any of the above embodiments of the first mounting rod 120, Fig.14 as well as Fig.15 As shown, in some embodiments, the friction member 320 is provided with a first through hole 321, and the first mounting rod 120 is inserted into the first through hole 321 and is slidably connected with the friction member 320. In this way, through the sleeve cooperation between the first through hole 321 and the first mounting rod 120, it is easy to realize the movement of the friction member 320 relative to the axial direction of the first mounting rod 120.

[0170] Based on any of the above embodiments of the first mounting rod 120, Fig.14 as well as Fig.15In some embodiments shown, the rotating member 310 can slide along the length direction of the first mounting rod 120, and the friction member 320 is slidably connected to the first mounting rod 120 and does not rotate relative to the first mounting rod 120. The rotating assembly 300 also includes an elastic assembly 700 disposed on the base assembly 100, and the elastic assembly 700 squeezes at least one of the rotating member 310 and the friction member 320. In this way, when the rotating member 310 drives the bearing member 200a to switch between the supporting state and the folding state, since the friction member 320 does not rotate, and the friction member 320 and the rotating member 310 can be slidably connected relative to the first mounting rod 120, when the elastic assembly 700 squeezes at least one of the rotating member 310 and the friction member 320, the elastic squeezing force can be used to increase the friction between the rotating member 310 and the friction member 320, thereby increasing the rotation damping of the rotating member 310. In this way, when the rotating member 310 is not driven by the rotational force, the supporting member 200 a can be fixed on the base assembly 100 , thereby improving the hovering effect of the folding mechanism 10 b.

[0171] That is, the elastic component 700 allows the rotating component 300 to be elastically telescopically moved along the length direction of the first mounting rod 120 , so as to increase the friction resistance between the rotating member 310 and the friction member 320 by utilizing the elastic squeezing force.

[0172] In other embodiments, the foldable electronic device 10 utilizes the rotating assembly 300 to allow the flexible display screen 10a to hover at any position between the folded state and the unfolded state.

[0173] It is understandable that the elastic component 700 cooperates with the friction component 320 to provide hovering damping for the rotating member 310, which is simple to operate and easy to adjust the rotation damping of the rotating member 310 by adjusting the elastic squeezing force of the elastic component 700 to meet the required hovering effect.

[0174] Furthermore, combined with Fig.12 or Fig.14 As shown, in some embodiments, the folding mechanism 10b further includes a damping cam 800 disposed on the first mounting rod 120, the elastic component 700 abuts against the damping cam 800, and at least one rotating member 310 is damped by the damping cam 800. Thus, by providing the damping cam 800, the rotation damping of the rotating member 310 can be further increased, and the hovering motion of the rotating member 310 can be easily realized.

[0175] Optionally, combined Fig.12As shown, in some embodiments, the damping cam 800 with damping cooperation rotating member 310 is a rotating member 310, the rotating member 310 is provided with a first arc groove and a first protrusion arranged at intervals along the outer periphery of its rotation axis, and the damping cam 800 is provided with a second arc groove matched with the first protrusion and a second protrusion matched with the first arc groove. When the rotating member 310 is in the first state, the first protrusion is arranged in the second arc groove, and the second protrusion is arranged in the first arc groove. When the rotating member 310 is in the second state, the second protrusion is against the first protrusion to squeeze the elastic component 700. In this way, when the rotating member 310 is in the first state, the first protrusion is arranged in the second arc groove, and the second protrusion is arranged in the first arc groove during the switching and rotation of the flexible display screen 10a between the unfolded state and the folded state, the damping cam 800 does not generate damping to the rotating member 310 or generates small damping, so that the folding mechanism 10b can be rotated conveniently to drive the flexible display screen 10a to move. At this time, the friction member 320 can be used to achieve a hovering effect of turning and stopping. When the rotating member 310 is in the second state, the flexible display screen 10a is in the unfolded state or the folded state. The second protrusion abuts against the first protrusion to squeeze the elastic component 700, thereby increasing the elastic deformation of the elastic component 700, thereby increasing the force of squeezing the friction member 320, and thereby increasing the rotation damping of the rotating member 310, so that the rotating component 300 needs to overcome a larger rotation damping to be able to move. That is, the rotating component 300 needs a larger driving force to rotate, so that the flexible display screen 10a can be fixed in the unfolded state or the folded state.

[0176] Based on any of the above embodiments, Fig.14 as well as Fig.15 As shown, in some embodiments, the base assembly 100 includes a stopper 130 fixedly connected to the first mounting rod 120, and the stopper 130 and the damping cam 800 are spaced apart along the length direction of the first mounting rod 120. The elastic assembly 700 includes at least one first elastic member 710, and at least one first elastic member 710 is sandwiched between the stopper 130 and the damping cam 800. In this way, through the cooperation between the stopper 130 and the damping cam 800, it is convenient to install the first elastic member 710 on the base assembly 100.

[0177] Optionally, the first elastic member 710 is sleeved on the first mounting rod 120. In this way, the two are more closely matched, which is conducive to achieving a lighter and thinner folding mechanism 10b.

[0178] Furthermore, combined with Fig.14As shown, in some embodiments, the base assembly 100 further includes a second mounting rod 140 fixedly disposed between the stopper 130 and the damping cam 800, and the elastic assembly 700 includes at least one second elastic member 720, and at least one second elastic member 720 is sleeved on the second mounting rod 140 and clamped between the stopper 130 and the damping cam 800. In this way, the at least one second elastic member 720 is sleeved on the second mounting rod 140 and clamped between the stopper 130 and the damping cam 800, so as to make full use of the internal space of the folding mechanism 10b to increase the number of elastic members, so as to flexibly adjust the rotation damping of the rotating member 310 and meet the hovering effect.

[0179] In addition, through the cooperation of the first mounting rod 120, the second mounting rod 140, the limit member 130 and the damping cam 800, it is convenient to modularly install the elastic component 700 on the base component 100, and then install the rotating component 300, which is beneficial to improve assembly efficiency.

[0180] It should be noted that there may be multiple specific implementations of the first elastic member 710 and / or the second elastic member 720. For example, the first elastic member 710 and / or the second elastic member 720 are compression springs or disc springs. For example, the first elastic member 710 and / or the second elastic member 720 are springs. For example, the first elastic member 710 and / or the second elastic member 720 are elastic rubber tubes (silicone tubes, rubber tubes, etc.). It should be noted that the present disclosure does not specifically limit the specific types of the first elastic member 710 and / or the second elastic member 720.

[0181] In addition, the number of the first elastic member 710 and / or the second elastic member 720 is not limited too much, as long as the number of the rotating member 310 can be realized with damping rotation.

[0182] Optionally, combined Fig.14 As shown, in some embodiments, the first elastic member 710 is a compression spring and is sleeved on the first mounting rod 120. In this way, the structure of the rotating assembly 300 is more compact. In addition, the elastic force of the first elastic member 710 is convenient to directly act on the damping cam 800.

[0183] Optionally, combined Fig.14 As shown, in some embodiments, the second elastic member 720 is a compression spring and is sleeved on the second mounting rod 140. In this way, the structure of the rotating assembly 300 is more compact. In addition, the elastic force of the first elastic member 710 is convenient to directly act on the damping cam 800.

[0184] It should be noted that the rotation range of the rotating member 310 for the hovering cooperation can be flexibly designed according to actual needs, such as 150°, 160°, 165°, 170°, 173°, 175°, 178°, 180°, etc.

[0185] It can be understood that the friction member 320 , the rotating member 310 and the damping cam 800 are made of wear-resistant materials, which is beneficial to improving the service life of the foldable electronic device 10 .

[0186] It can be understood that the hovering effect of the rotating member 310 is achieved by the friction resistance generated by the friction member 320. If the friction coefficient of the friction member 320 is large, it is easy to wear, and after wear, the friction resistance generated by the friction member 320 will also become smaller, which is not conducive to providing the foldable electronic device 10 with a hovering effect for a long time. Fig.10 As shown, in some embodiments, the friction member 320 is provided with a first friction surface 323, the rotating member 310 is provided with a second friction surface 313 that is frictionally matched with the first friction surface 323, and at least one of the first friction surface 323 and the second friction surface 323 is provided with an oil storage recess (not shown). In this way, the oil storage recess is used to store lubricating oil to lubricate the friction member 320 and the rotating member 310, reduce the friction coefficient between the friction member 320 and the rotating member 310, and improve the wear resistance of the two, thereby providing the foldable electronic device 10 with a hovering effect for a long time.

[0187] Combination Figures 1 to 13 as well as Fig.17 As shown, in some embodiments, the foldable electronic device 10 further includes a housing assembly, the housing assembly includes a first housing 101 and a second housing 102, and the folding mechanism 10b is disposed in the housing assembly. The folding mechanism 10b includes two groups of bearings 200a spaced apart on both sides of the base assembly 100 and a rotating assembly 300 corresponding to the bearings 200a one by one, the two groups of bearings 200a and the rotating assembly 300 move synchronously in opposite directions relative to the base assembly 100, and one of the bearings 200a is fixedly connected to the first housing 101, and the other bearing 200a is fixedly connected to the second housing 102. The flexible display screen 10a covers the first housing 101, the folding mechanism 10b and the second housing 102. In this way, when the foldable electronic device 10 is in use, the rotating components 300 on both sides of the base component 100 rotate around the base component 100, and the supporting component 200a can be driven to rotate through the rotating member 310, so that the first shell 101 and the second shell 102 move synchronously in opposite directions to realize the flexible display screen 10a switching between the unfolded state and the folded state.

[0188] Based on the above embodiments, Fig.13 as well as Fig.17As shown, in some embodiments, the rotating assembly 300 and the bearing member 200a correspond to each other as a second group, and the folding mechanism 10b further includes a synchronization assembly 900. The two second groups are arranged on both sides of the base assembly 100, and the two bearing members 200a are synchronously moved by the synchronization assembly 900 so that the two bearing members 200a are in a folded state or a supported state. In this way, the synchronization assembly 900 is used to facilitate the synchronous rotation of the two second groups of rotating members 310, so as to realize the synchronous movement of the two groups of rotating members 310, so as to drive the bearing member 200a to switch between the folded state and the supported state. Moreover, the spacing between the two groups of rotating members 310 can be flexibly adjusted.

[0189] It should be noted that there are many ways to implement the synchronization component 900, including but not limited to the meshing transmission of the synchronization gear 910, and also include other ways to implement synchronous rotation, such as a pulley mechanism, a sprocket mechanism, etc.

[0190] Furthermore, if Fig. 9 As shown, in some embodiments, the synchronization assembly 900 includes at least one synchronization gear 910, and the rotating member 310 includes a gear body meshed with at least one synchronization gear 910. In this way, the gear body is directly or indirectly meshed with at least one synchronization gear 910 to achieve synchronous and reverse rotation of the two sets of rotating members 310. The structure is compact and easy to implement.

[0191] In combination with the above-mentioned embodiment of the first mounting rod 120, as Fig.14 As shown, in an exemplary embodiment, the base assembly 100 includes two first mounting rods 120 spaced apart, a group of rotating members 310 is disposed on one first mounting rod 120, and another group of rotating members 310 is disposed on another first mounting rod 120. The synchronization assembly 900 is disposed between the two first mounting rods 120. The friction member 320 is disposed on the two first mounting rods 120, and one end of the friction member 320 is clamped between one group of rotating members 310, and the other end of the friction member 320 is clamped between the other group of rotating members 310.

[0192] Furthermore, combined with Fig.14 As shown, in some embodiments, the base assembly 100 further includes a third mounting rod 150 sandwiched between the two sets of rotating assemblies 300, and the synchronous gear 910 is rotatably connected to the third mounting rod 150. In this way, the third mounting rod 150 is used to facilitate the rotatable arrangement of the synchronous gear 910 on the base assembly 100.

[0193] Combination Fig.14As shown, in one example, the friction member 320 is provided with a second through hole 322, and the third mounting rod 150 is inserted into the second through hole 322 and is slidably connected with the friction member 320. In this way, through the sleeve cooperation between the second through hole 322 and the third mounting rod 150, it is easy to realize the axial movement of the friction member 320 relative to the third mounting rod 150.

[0194] In addition, the friction member 320 is respectively connected to the two first mounting rods 120 and the third mounting rod 150. The connection is reliable, and friction cooperation with the two sets of rotating members 310 is achieved, which is conducive to reducing assembly procedures and improving the assembly efficiency of the rotating assembly 300.

[0195] In other embodiments, the friction members 320 that frictionally cooperate with one set of rotating members 310 are one set, and the friction members 320 that frictionally cooperate with another set of rotating members 310 are another set. The two sets of friction members 320 are respectively mounted on the base assembly 100.

[0196] It can be understood that the rotating component 300 combines the rotating component 300, the elastic component 700 and the synchronization component 900 into a module through the base component 100, and then assembles it with the base component 100 through the first mounting rod 120 and the third mounting rod 150 to achieve modular installation in the folding mechanism 10b, which is beneficial to improve assembly efficiency.

[0197] It should be noted that there are many ways to install the first mounting rod 120 and / or the third mounting rod 150 on the base assembly 100, including but not limited to shaft connection, screw connection, snap connection, riveting, welding, etc.

[0198] It should be noted that the "third mounting rod 150" can be one of the parts of the module of the "frame assembly 100", that is, it can be assembled into a module with the "other components of the frame assembly 100" and then assembled modularly; it can also be relatively independent of the "other components of the frame assembly 100" and can be installed separately, that is, it can form a whole with the "other components of the frame assembly 100" in this device.

[0199] It should be noted that the "connecting rod 330" can be one of the parts of the module "rotating component 300", that is, it can be assembled into a module with the "other components of the rotating component 300", and then modularly assembled; it can also be relatively independent of the "other components of the rotating component 300", and can be installed separately, that is, it can form a whole with the "other components of the rotating component 300" in this device.

[0200] Equivalently, the components included in the "assembly", "component", "mechanism" and "equipment" of the present disclosure can also be flexibly combined, that is, modular production can be carried out according to actual conditions, modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device. The division of the above components in the present disclosure is only one embodiment, for the convenience of reading, and not to limit the scope of protection of the present disclosure. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of the present disclosure.

[0201] It should be noted that the foldable electronic device 10 in any of the above embodiments includes but is not limited to a foldable display device, a foldable smart phone, a foldable tablet computer, etc.

[0202] It should be noted that the accessory of the electronic device includes the folding mechanism in any of the above embodiments.
